DEEr-WELL PUMP.

To all 'whom it may concern: 4 Y

Be it known that I, FRED J. I-IAMLIN, a citizen of the United. States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Deep-Well Pumps, of which the following is `afull, clear, and exact description, suchA as/will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to double acting pumping cylinders, and more particularly to deep well pumps.

An objectof the improved invention is to provide a pump that will pump water containing a small quantity of sand without clogging or rendering the pump inoperative.

Another object of the improved invention is to construct a hollow plunger rod with a valveless unobstructed discharge end so that the water may flow freely therethrough wit-hout great resistance.

Another object of the improved invention is toconstruct a pum that will reduce the so called valve knocking which is so detrimental and destructive to the operation of deep well pumps.

Another object of the improved invention is to construct a pump provided with as free passageway as possible to reduce the resistance when water is pumped therethrough.

Another object of the improved invention is to provide a valve in the piston of the pump for the purpose of discharging water from the cylinder into the discharge pipe formed by the hollow piston rod.

Another object of the improved invention is to provide a pump with a large ring valve to open and close a series of circumferentially arranged intake ports.

With these and other objects in view the invention consists inV the features of construction, combinations and arrangements of parts hereinafter described, illustrated in the accompanying drawings and more particularly pointed out in the appended claims.

In the drawings Figure 1,v is a view in elevation ofthe improved pump with certain parts broken away to show the interior thereof.

21 and the center of the bottom head provided with a threaded hole to receive the fluted guide rod 22, the valve seat 23 being tightly fitted on rod 22 and against the upper surface of the bottom head 15.

The frusto-conical shaped valve 24 seating Von seats 21 Aand 23 is provided with a boss 25 integrally connected to the -frusto-conical shaped valve by ribs 26, the valve sliding up and down on iluted rod 22 and the sliding j movement being limited by and between head 27 of the rod 22 and the valve seats 21 and 23. The object of the iuted rod being t0 allow vsand to pass between the boss and rod and prevent binding and clogglng- The intake port casting 28 with lower annular flange 29 is securedby bolts 30 to l annular `iange 31 integral with cylinder 19, the series of ports 32 circumferentially arranged and allowing a greater volume of water to enter with less resistance than in ordinary pumps.

The wall 33 integral with and extending upwardly from the port lcasting 28 forms a guide for the flat ring valve 34 seating on seat 35 secured to the casting by screws 36 l through holes 37 and are held thereagainst4` by springs ,381,` the springs compressed.

against the ring by the upper end bearing against the upper cylinder head casting 39."

o enino- 47 are bolted tooether bybolts 48.

P h a e.

The wall 49 integral with 'and Vrising upward from the. upper head casting forming a support for the valve seat 50 merges into a flange 51 bolted by bolts 52 to the flange 53 integral withvthe reducer 54 which is screwedon the well pipe 55.`

The valve 56 seating .on seats 50 and 57, the .latter tightly tted on boss 41 and against upper headr 39', is provided with vintegral ribs 58 which are arrangedl to loosely slideon the boss 41;

The hollow plunger rod 42 is free from valves or other obstructions near the upper end and provided with slotted openings 59 to discharge water while the eXtreme upper end 60 is internally threaded to screwonto the end `of the connecting plunger rod 61, the lower end of the plungerl rod'42 being threaded and engaging rings 63, 64 and 65 separating leather washers 66,167" and 68 while rings 69, `and 71 separate leather washers72, 73 and 74.

TheV leather washers 66, 67 and 68 are turned upward'compressing against the side of the cylinder while washers 72,73 and 74 are turned downward compressing against the cylinder, the washers turned upWa-rd forming packing Trings* for the upward The rings 63,364, 65, 75, 69, `70 and-71 andwashers'66, 67,l 68, 72,73' and 7 4 are secured together by bolts 76.4

Thepiston valvev frame 77 provided with openings 78 and screwed intoV the lowery rings69, 7O1and 7l supports the valveseat 79 drivenron the luted valve guide' rodd 80 screwed into thetcentervof the iiame -7 7 'and the valve seat 81 fits tight on `rod-8O against frame 77.

The piston valve 82 integrally connected with boss 83 by ribs 84 is arranged to slide limited by head 85 and valve seats 79 and 81.

In operation on each upward stroke the piston sucks water through the jacket opening. 47, openings 86 raising valve 24 and passing into the cylinder until the piston 1 reaches the top of the stroke.

On the downward stroke the water drawn into the cylinder by the lower valve `24 closes the valve and 4is forced upward throughthe openings 78, valve 82, pipe 42",A

slotted openings 59 Yand upward through pipe 55. Y

On each downward stroke the pistonsucks Water through ports 32 raising thefring valve 34 and filling the cylinder with water until the piston reaches the bottom-of the stroke and on returning closes tlie-ports32 by compressing ring valve'34-f against valveV seat 35 and forcing the-water through openings 87 inthe upper Vcylinder `head- 39 then raising valve 56 passing upwardthroughreducer 54 and'upwardi-through pipe 55.#`

The' chier' advantage ofthev constiuction-` and operation hereinbefore 4described isvin the durable constructionof the parts and arrangements of the wide openings which serve as portsandare asl free from resistance as possible.

Having thus described'my invention, what 1 claim as new and desirelto secure by Letters Patent, is
